ASC702: Using an NGC system in fixed antenna applications

Course details

Summary
  • Using the CPI NGC controller in fixed, motorized antenna applications.

Description

This course is intended for earth station technicians with NGC "User" level access who are responsible fo day-to-day operation and maintenance of NGC-controlled antenna systems. A typical fixed, motorized 4.9m antenna system is explained in detail, and variations and options are described.

Audience:

Earth station technicians with NGC "User" level access who are responsible fo day-to-day operation and maintenance of NGC-controlled antenna systems. Techs and engineers who will be contininuing with higher level NGC training courses.

Prerequisites:

Recommended: GVF 530+531+532. Required: ASC 701.

Delivery:

Animated & interactive HTML/Flash, self-paced, on-line format. Requires Internet access while studying the course material. High speed access is preferred but is NOT required. Student's computer must have a current browser and the current version of the Adobe Flash player (free) installed.
